A Meta-Learning Framework for Multitask Reverberation Mapping in Active Galactic Nuclei

Aman N. Raju, Andjelka B. Kovačević, Andjelka B. Kovačević +15

The Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) is expected to observe active galactic nuclei (AGN) at sky densities of approximately 1000-4000 per sq. deg, en…

Gaia GraL: Gaia DR2 Gravitational Lens Systems. IV. Keck/LRIS spectroscopic confirmation of GRAL113100-441959 and model prediction of time-delays

Olivier Wertz, Daniel Stern, Alberto Krone-Martins +14

We report the spectroscopic confirmation and modeling of the quadruply imaged quasar GRAL113100-441959, the first gravitational lens (GL) to be discovered mainly from astrometric c…

GraL spectroscopic identification of multiply imaged quasars

Priyanka Jalan, Vibhore Negi, Jean Surdej +24

Gravitational lensing is proven to be one of the most efficient tools for studying the Universe. The spectral confirmation of such sources requires extensive calibration. This pape…

Anisotropies in the astrophysical gravitational-wave background: Predictions for the detection of compact binaries by LIGO and Virgo

Alexander C. Jenkins, Mairi Sakellariadou, Tania Regimbau +1

We develop a detailed anisotropic model for the astrophysical gravitational-wave background, including binary mergers of two stellar-mass black holes, two neutron stars, or one of…

Gaia GraL: Gaia DR2 Gravitational Lens Systems. VII. XMM-Newton Observations of Lensed Quasars

Thomas Connor, Daniel Stern, Alberto Krone-Martins +23

We present XMM-Newton X-ray observations of nine confirmed lensed quasars at identified by the Gaia Gravitational Lens program. Eight systems are strongly…
